I.-On the part taken, by Oxide of Iron and Alumina in the Absovtive Action of Soils. * Jour. Chem. SOC. [2J, iv, 296. 4 The ferric oxide absorbed 95.7 per cent. of the phosphoric acid present, the The aliimina absorbed 96.8 per cent. of whole of the calcium remained in aolution. the phosphoric acid, and 95.6 per cent. of the calcium remained dissolved.

Structural, Spectral, Electric-Field-Induced Second Harmonic, and Theoretical Study of Ni(II), Cu(II), Zn(II), and VO(II) Complexes with [N2O2] Unsymmetrical Schiff Bases of S-Methylisothiosemicarbazide Derivatives

“…[6][7][8][9][10][11] In recent years, the chemistry of bis(salicylidene)-Salkylisothiosemicarbazone complexes, analogues of salentype complexes where S-alkylisothiosemicarbazide is used as the diamine moiety instead of ethylenediamine, has been thoroughly studied. 12,13 S-Alkylisothiosemicarbazide is especially interesting for the assembling of asymmetric systems because of the nonequivalence of its terminal amino groups. Owing to the high activity of the 2-hydroxybenzaldehyde unit, however, preparation of the asymmetric tetradentate monosalicylidene-isothiosemicarbazide species [14][15][16][17] is nontrivial.…”

Crystal structure of (E)-N-cyclohexyl-2-(2-hydroxy-3-methylbenzylidene)hydrazine-1-carbothioamide

“…Thiosemicarbazone Schiff base compounds have soft sulfur and hard nitrogen as well hard oxygen atoms (Mohamed et al, 2009). These Schiff base compounds are of special interest because of their diversity in coordinating to hard and soft metals using the hard and soft coordinating sites such as NSO (Arion et al, 2001;Leovac & Č ešljević, 2002;Chandra & Sangeetika, 2004;Singh et al, 2000;Gerbeleu et al, 2008;Mohamed et al, 2009). Many Schiff base compounds and their complexes with transition metals have wide biological and pharmaceutical applications (Padhyé & Kauffman, 1985;Salam et al, 2012b).…”

Crystal structure of (E)-2-[3-(tert-butyl)-2-hydroxybenzylidene]-N-cyclohexylhydrazine-1-carbothioamide

“…The thiosemicarbazone Schiff base is comprised of two soft Lewis bases -the sulfur and nitrogen coordinating sites as well as a hard Lewis base -the oxygen atom (Mohamed et al, 2009). Such Schiff bases are of special interest because of their specific coordinating ability to some metal ions (Arion et al, 2001;Leovac & Č ešljević, 2002;Chandra & Sangeetika, 2004;Singh et al, 2000;Gerbeleu et al, 2008;Mohamed et al, 2009). Several reports have highlighted the importance of the chelate metal complexes of thiosemicarbazone Schiff bases for medicinal applications, particularly against cancer (Paterson & Donnelly, 2011;Ziessel, 2001;Salam et al, 2012;Arafath et al, 2017a).…”
